It certainly takes longer to recover from strenuous activity. I'm not a doctor, but I would imagine that plays into it quite bit. Backpacking at altitude is a lot different than at lower elevations for many reasons. The cumulative effect is definitely there.
Correa isn't expected to travel with the team to Colorado. That sucks, but as long as he's ready for the playoffs, I'm fine with that.
The team has said that he hasn't had a setback.
I actually like that they went with what basically amounts to an all out youth movement for the day. Now's the perfect time to have some fun like that.
Sonny may not even pitch 5 innings anyway.
With so much discussion so early in the game thread, which is great to see, I just wanted to jump in and let everyone know that I added the A's lineup to the OP.
